Create a vibrant cartoon scene bursting with energy and color, channeling the whimsical style of iconic illustrators.

In the foreground, center a large, round hot tub filled with bubbly water, featuring exaggerated steam spirals rising up. Four cartoonish characters with comically large heads and wide smiles are lounging in the hot tub, each holding a cocktail glass filled with colorful, oversized fruit garnishes. The characters have exaggerated features reminiscent of Peanuts and Calvin and Hobbes, with expressive eyes and playful postures.

Perched at the edge of the hot tub, a gigantic, triple-layered birthday cake towers high. It's covered in bright frosting swirls of electric pink, neon green, and sky blue, topped with a "19" candle that looks like it's about to tip over due to its comical size. The cake's base has an animated quality, reminiscent of Winsor McCay’s dream-like creations, almost like it might start to wibble-wobble.

Floating in the pool, a colorful inflatable raft holds a variety of cartoon cocktails, each with a decorative mini umbrella. The cocktails are in playful, stylized glassware, echoing the vintage charm of R. Crumb’s quirky creations.

Above the hot tub scene, a cheerful banner strung between two palm trees reads "Happy 19th Birthday!" in large, bold letters. In the corner of the banner, the name "Nelly" is scrawled in a playful, hand-drawn font, as though added last-minute by a friend. The palm trees are drawn with exaggerated, angular leaves in a nod to Hergé’s precise style, and coconuts hang down comically large and low.

The background sets the scene on a sunlit holiday resort. Cartoon clouds float lazily in a deep blue sky, their shapes reminiscent of Gary Larson’s oddball style. In the distance, a sprawling beach with exaggeratedly large sandcastles sits next to a calm, turquoise ocean, rendered with the detail and charm of a classic Walt Disney animation.

Scatter a few seagulls in the sky, their features exaggerated like Osamu Tezuka’s manga characters, giving them a playful presence. Add a comically large beach ball rolling across the sand, with its bright colors and whimsical motion inspired by Charles Schulz.

This vibrant, colorful illustration combines multiple influences to create a unique, playful, and visually detailed birthday card cover that captures the spirit of celebration and fun.
